2 Claims. 1

This invention. relates tcimprovements in brushesand it has referencemore particularly to novel features in the, construction of paintbrushes; it being the principal object of this invention toprovidejbrush heads made in laminations and which may be interchangeablyused in the same brush handle, and which heads may be made up of variousnumber of 'brush head sections or laminations as required or desired forany particular use.

It is also anobjectof this :invention to provide brush head laminationsthat may be assembled in various numbers in an interlocked relationshipand applied within*v the clamping jaws ofthe handie portion; the jawsybeing adjustable to receive and hold brush headsof one` or morelaminations.

Still anotherobject ofV the invention is to Aprovide an irnprovedtypeYofbrush handle including a pair of jawsthat are arrangedto holda brushhead between themV andy are adjustable by means of a nut located attheouter enclfof the handle.

Still another object of the invention is to pro,- vide aA brush thatpermits quickA and. easy removal of a brush head therefrom and theseparation of the laminations making up the head for quick and eiectivecleaning of the bristles.

Still further objects of the invention reside in the details ofconstruction of parts; in their relationship and mode of operation aswill hereinafter be fully described.

In accomplishing these and other objects of the invention, I haveprovided the improved dedetails of construction, the preferred forms ofwhich are illustrated in the accompanying drawings, whereini Fig. 1 is aside view of a brush embodying the novel features of the presentinvention.

Fig. 2 is a longitudinal, sectional View of the same, showing the brushhandle jaws opened apart for reception of or removal of the brush head.

Fig. 3 is a perspective View of a single section or lamination used inmaking up a brush head.

Fig. 4 is an end View of a brush head comprising two assembledlaminations.

Referring more in detail to the drawing-d The present brush comprises ametal handle portion and a. brush head portion. The handle is designatedgenerally in Fig. 1 by reference character H and the brush head byreference character B. The brush head may comprise one or more similarlymade brush sections or laminations I0, one of which is shown in Fig. 3as comprising a pack of bristles I2 with upper ends bound by anenclosing metal band I3. Each section,4 or lamination, of .the brushwould beto-i .the full width Aci thexbrush head, but-relatively thin;as. ,illustrated and.: itis the: intent. that ,such laminationsbeAassembled.face te; face., as seen `in Fig. ;2',..and used- VVin anyreduired number to ,make up a. brushheadlof Varequired-,thieleness forthe Work being done.

.In order. thatthese laminationsinay `be held in an exact .and properrelationshinwhen saassemhled,. I have provided :the bndingstrp .l'3 ateach sidecf the section .or lamina-tien with al1-.indenture,.-as at .laandi ,aprotnberarnce or Yboss as 4at i6; these being oppositelyarrangedionaopposite sides or" rthe section.7 In the assembling of vthelaminations, 4face to face the nrotuberances I6 ,willl seat within theindentures I5 of the other aand .theseare so arranged:thatthe,sections-will thereby Ibe held irl-.an exactregistraiton asunderstood by reference .to Fig, 4..

It is further to be understood that brush heads .may be madenn.otone,.two, ,three yor more 1aminations.

The handle portion of the brush .Qomprisesthe `opposite side sectionsZtl-2.9;, alikein shape yand ot the same'size. lAtther rupper endsythese-sections are joined by a resilient cross piece ZI in spacedrelationship. The lower end portions of the opposite side sections20--20 are spaced apart and served as jaws to receive and hold the brushY head between them.

The opposite side sections of the handle have flat, and somewhatwidened, jaw portions 22 at their lower ends, designed to embrace thebrush head between them, and each of these jaw p0rtions is formed withan indenture 25 and a boss 26 at the same spacing as those of the brushhead sections. Therefore, when the brush head is assembled, and itsupper end portion placed between the jaws 22-22, these parts may beclamped together to grip the head therebetween, and in so doing, theprotuberances It of the outside laminations of the brush head will beseated in the recesses 25 of the brush head and their indentures I 5will receive the jaw protuberances so that the head will be held secure.

The clamping action of the handle sections is eilected by means bestshown in Fig. 2, wherein it is noted that a rod 30 is located lengthwiseof and between the opposite side sections of the handle. At its upperend, this rod passes through a centrally located hole SI in the piece 2|and is equipped at its top end with a turning button 32. The lower endportion of the rod is threaded, as at 33, and is adjustable within atubular extension 34 which, at its lower end, has an extension 35 xedtherein, and pivoted in the lower end of this extension member aretoggle levers or links 36-36 that are in the crank shaft form shown inFig. 1, with crank ends pivoted on the handle jaw portions. Thearrangement of parts is such that when the rod 3U is turned in onedirection by means of the button 32, the toggle linkage wil be expandedand the jaw spread apart. Then when turned in the other direction, thetoggle will be retracted and the jaws will be drawn together and therebyclamped against the brush head to hold it in place. Adjustments may bequickly and easily made and brushes of one or more laminations used andheld securely in place between the jaws.

One advantage in this brush construction resides in the provision forseparation of laminations for easy and quick cleaning of the brush andhandle. Another advantage is the possibility of making up brushes ofdierent weight or thickness to meet the job at hand. Still anotheradvantage is the requirement of only one handle for any number of brushcombinations. The inter-engaging of the protuberances of the laminationswith the indentures provides for secure holding of the laminations inthe handle so long Aas the jaws are clamped, but easy separation forcleaning when unclamped.

While in the foregoing description and in the drawings I have describedand shown a brush head of one width only, it is to be understood thatthe brush head may be made in Various widths, as has been indicated inthe dotted line shown in Fig. 1.

Furthermore, it is to be understood that by the assembling oflaminations of varying widths a brush head may be built up of a,substantially oval shape; that is. by using wider laminations in thecentral portions of the brush head and narrower laminations toward theoutside of the 40 brush head.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent is: l. A paint brush comprising a,brush head made up of a plurality of independent bristle sections,

each equipped with a metal binding about one end, and said bindings ofadjacent sections being disposed in face to face relationship and withparts of bindings of adjacent sections interengaged and a handlecomprising coextensive opposite side portions serving as oppositelyrelated gripping jaws at corresponding ends for receiving the brush headbetween them and joined at their outer ends in a manner to permit thejaw portions to be moved from and toward each other and a toggle linkagebetween and connecting the jaw portions of the handle and an adjustingshaft for the toggle disposed longitudinally within the handle andextending beyond the joined ends thereof and operable to adjust the saidside portions of the handle to move the jaws from and into grippingcontact with the brush head when placed between them.

2. A device as in claim l wherein said adjusting shaft includes atubular inner section attached to the toggle linkage and an outer endsection rotatably held against longitudinal movement in the handle andthreaded into the tubular section and equipped at its outer end with aturning button.
